In this paper, we investigate the massless Reissner–Nordstrom de Sitter metric in the context of minimal length scenarios. We prove not only the confinement of the energy density of massless charged particles, both fermions and bosons, but also their ability to tunnel through the cosmological horizon. These massless particles might be interacting with Dirac sea and in this case they will appear outside the cosmological horizon in the context of dS/CFT holography. This result may formulate a fundamental reason for the expansion of the Dirac sea. Therefore, a spacetime Big Crunch may occur.

无质量带电粒子从 RN-dS 视界和线性和二次 GUP 隧道辐射

在本文中，我们在最小长度场景中研究了无质量 Reissner-Nordstrom de Sitter 度量。我们不仅证明了无质量带电粒子（费米子和玻色子）的能量密度的限制，而且证明了它们穿越宇宙视界的能力。这些无质量粒子可能与狄拉克海相互作用，在这种情况下，它们将出现在 dS/CFT 全息背景下的宇宙视界之外。这一结果可能是狄拉克海扩张的根本原因。因此，时空大崩盘可能会发生。
